gistsafe 0.1.2

Secure secret management using encrypted GitHub Gists

GistSafe

Encrypted secret management for developers. Store environment variables securely in private GitHub Gists.

Features

• Strong encryption via PBKDF2HMAC-SHA256 + Fernet
• Private GitHub Gists as storage — no infrastructure to manage
• Per-project, per-environment secret organization
• Inject secrets as environment variables into any command
• Optional key obfuscation (encrypts variable names too)
• Password hints for recovery
• Local caching for fast lookups

Installation

pip install gistsafe

Or with pipx (recommended for CLI tools):

pipx install gistsafe

From source:

git clone https://github.com/moringaman/gistsafe.git
cd gistsafe
pip install .

Setup

Create a .env file in your project directory, or set the environment variable:

export GITHUB_TOKEN=ghp_yourtokenhere

You need a GitHub personal access token with the gist scope.

Requirements: Python 3.10+

Quick Start

# Create secrets for a project
gistsafe create --project myapp --environment dev
# → prompts for key/value pairs and an encryption password

# View secrets
gistsafe get --project myapp --environment dev

# Run a command with secrets injected as env vars
gistsafe inject --project myapp --environment dev -- npm start

# List all projects
gistsafe list

Usage

Creating Secrets

gistsafe create --project myapp --environment dev

Options:

• --password-hint "Office wifi password" — hint shown before password prompt
• --obfuscate-keys — encrypts key names as well as values

With obfuscation enabled, DATABASE_URL in storage becomes gAAAAABk7X.... Original names are restored on retrieval.

Updating Secrets

gistsafe update --project myapp --environment dev

Shows current secrets first, then prompts for new values. Unchanged secrets are preserved.

Retrieving Secrets

gistsafe get --project myapp --environment dev

If a password hint was set, it displays before the password prompt.

Injecting Secrets into Commands

gistsafe inject --project myapp --environment prod -- npm start
gistsafe inject --project myapp -- npm test
gistsafe inject --project myapp -- printenv API_KEY

The inject command decrypts secrets, uppercases the keys, sets them as environment variables, and runs your command. If --environment is omitted, it uses NODE_ENV (defaulting to development).

Listing Projects

gistsafe list

Shows all projects, their environments, and gist URLs in a table.

Secrets are encrypted client-side with your password before touching the network. GitHub never sees plaintext.

Caching

GistSafe maintains a local index at ~/.gistsafe/cache.json to avoid hammering the GitHub API. The cache:

• Stores project names, environments, and gist IDs (never secrets)
• Auto-refreshes in the background when stale (>1 hour)
• Updates immediately on create/update operations
• Falls back to direct API search on cache miss

Security

What's Protected

• All secrets are encrypted with PBKDF2HMAC-SHA256 (100,000 iterations) + Fernet before storage
• Encryption password never leaves your machine
• Gists are created as private by default
• Optional key obfuscation hides variable names in storage

Limitations

GistSafe is designed for development and personal projects. It is not suitable for:

• Production environments
• Regulated industries (finance, healthcare)
• Applications requiring SOC2, HIPAA, or PCI compliance

For production use, consider HashiCorp Vault, AWS Secrets Manager, Doppler, or Infisical.

Best Practices

• Use strong, unique passwords per project
• Rotate GitHub tokens regularly
• Enable 2FA on your GitHub account
• Use key obfuscation for sensitive projects
• Never include the actual password in hints

Development

git clone https://github.com/moringaman/gistsafe.git
cd gistsafe
python -m venv .venv
source .venv/bin/activate
pip install -e .

Run tests:

# Test crypto roundtrip
python -c "from gistsafe.crypto import encrypt_value, decrypt_value; import os; s=os.urandom(16); v,s2=encrypt_value('test','pw',s); assert decrypt_value(v,'pw',s2)=='test'; print('OK')"
